SANSI Grow Light Bulbs for Indoor Plants, 24W Full Spectrum 4000K Daylight

I picked this up about a month or two ago because a few of my houseplants were clearly struggling in my apartment's low light, and I didn't want to keep watching them slowly decline. I wasn't expecting miracles, but I have to say this light has been worth it. The difference in my plants hasn't been overnight or dramatic, but it's been real and consistent. New leaves coming in, better color, less of that sad droopy look I was used to seeing. That's honestly all I needed to see to feel good about the purchase. The brightness and coverage surprised me. It throws a lot of usable light across a decent area — more than I expected from a single bulb. My plants aren't all crammed directly underneath it and they're still benefiting, which is a nice bonus when you're working with limited space. The fact that it screws into a regular socket is a bigger deal than it sounds. I already had a clamp light I wasn't really using — swapped the bulb in, clamped it right onto my shelf, aimed it at my plants, and that was it. No special hardware, no complicated setup, just plug and go. A couple things to keep in mind: it is a bright light, so if you're putting it in a living space you'll probably want to put it on a timer rather than leaving it on all day. And it does run a little warm, which I expected but is worth knowing. Overall, solid product. Nothing flashy, just works. For the price and the simplicity, I'd buy it again.

First image is first day of use, second image is today after 2 months of use. 1. Plant recovery: my basil plant was in poor condition and looked like it was going to die, but it recovered after we started using this bulb 2. Growth: the plant became significantly fuller and began producing much more basil 3. Brightness: the bulb is extremely bright and provides strong, consistent light 4. Results: we now harvest enough basil to dry and blend instead of purchasing dried basil from the store 5. Value: we originally paid $24 for the plant and spent about $72 total on this bulb and a compatible lamp, but the results made it worthwhile 6. Visible difference: the before-and-after photos clearly show how much healthier and fuller the plant became Real use: We bought this light after our basil plant started looking weak and damaged. After two months under the light, it did not just recover, it grew enough basil for us to begin drying and blending our own herbs. Cons: I have not experienced any meaningful drawbacks. The bulb is extremely bright, but that is exactly what I wanted from a grow light. Bottom line: This bulb is unbelievable. I would love to create a three-week time-lapse to show how quickly it helps the basil grow. I love the results, but I am sure my basil plant loves it even more.

With just north facing windows and a building across the way casting a shadow into our unit, we don't get nearly enough sunlight for healthy plants so I went with this 24W and its been doing a tremendous job. As you can tell from the picture, we're getting lots of golden coloring on the pothos (prior it was all green leafage), healthy new shoots from the ZZ plant, and the peace lily is flowering again - all great signs that the light is doing its job. The light does get warm but I rigged up an old pc fan with a spare adapter to turn on as needed to dissipate as much heat from the housing. Energy usage is a slight blip up but nothing major. So far I'd rate it 5 stars but Sansi reliability and long term usage is a point of contention in other reviews I've read. I will wait to see how long this lamp lasts for before updating my review but so far so good.

I have these situated over my jades, a couple of euphorbias, and a dish of assorted smaller succulents. These are a total game-changer for those of us trying to grow heat and sun-loving plants in the wintertime. I’m even getting that nice sun blush that makes succulents even more beautiful. Also great for a little rehab for a plant that needs some TLC. I recommend these lights whenever someone asks about grow lights. These lights haven’t really impacted my electricity bill. If you’re looking for grow lights and want to avoid higher energy costs, LEDs are a great option, they’re very efficient. UPDATE SPRING 2020: I thought I would add some updated photos, see the ones labeled “Spring 2020.” I am still really happy with these bulbs. I got them in the fall of 2019, so this photo represents about 7 months of use. I keep adding more plants to the area around them. Plants love these lights! UPDATE WINTER 2021: I now have five of these bulbs total, I just added two more. Something I am learning is you HAVE to allow for heat dissipation with these or they might fail on you! Four days ago, I changed some of the shades to ones that looked better but trapped the heat in more, especially on top. Today, four days into this new setup, two of my older bulbs began to flicker and one of them went out completely. I realized it either had to be a helluva coincidence or my new shade setup was damaging the bulbs. A quick google confirmed this suspicion. Learn from my mistake! Also, take a look at all the bad reviews here. In the ones that have a photo, you can see they have the bulb in a fixture that doesn’t allow the heat to escape. Sansi isn’t to blame for this, they do warn about proper installation, but I think they should perhaps have more prominent and detailed instruction about using these bulbs in fixtures or with shades. If your bulb fails and it wasn’t the fixture, make sure to contact Sansi. These come with a 5-year unlimited warranty. I won’t be doing that because my situation is user error, but it seems a lot of the people who left negative reviews could have simply asked for a replacement.

Value for the money. Keeps my plants with plenty of light during the winter.Essy to use. Easy to install. No noise going on 2 years old. Excellent

Testing the 30W daylight as an aquarium light on a 40 gallon, planted Walstad tank. So far the plants seem to love it, and the growth has been much more lush with larger leaves, thicker too. The red toned plants such as bacopa and rotala rotundifolia had stayed green up until I added this light to the tank lighting array. Now the bacopa is turning that rich reddish brown it is supposed to be and the rotala is getting the pink flush on its leaves. The hornwort is so dense and lush its incredible compared to its brethren on the outer edge of the tank which don't get this light. I'm using this clamp light holder as the lamp: Adjustable LED Clamp Lighting Mount/clip Holder E27 Socket Gooseneck Clamp / Mount The gooseneck bends nicely and I currently have the the light suspended about 10 inches above the water. It is a supplemental light to 2 of these: EcoSmart 120W Equivalent Day Light PAR38 Dimmable LED Flood Light Bulb (2-Pack) that I'm also using on this tank. I bought the Ecosmart LED flood lights at Home Depot for $14.99 for a 2 pack so only rougly $7.50 a bulb and they are great. I don't know how much of the plant growth can be contributed to the additional light spectrum they provide. They each have a 40 degree spread whereas this Sansi light has a wider 60 degree spread, so I get some overlap. This is a benefit on the one hand but does mean seeing a little bit of bright glare from the side view of the light. Thankfully the light holder (purchased separately as described above) is adjustable to many angles so I just tilt it in towards the wall a bit. One downside is that it's not as bright as I was hoping. I wanted to suspend it even higher above the water to get the ripply effect in the water, and to keep the LEDs well above the eyes of the livestock when they feed, sort of more like the sun, instead of them having harsh LEDs directly in their eyeballs like specialized aquarium LEDs seem to do. Sansi do make a brighter 40W version but it's rather expensive at $39.99. I might splurge though as the plant growth is so impressive. My cherry shrimp seem to like it too as I often find them up in the foliage now, basking in the light since adding it. Overall I like it but wish the price wasn't so high and wish there was a version which eliminated the slight ring of side glare for aquariums where the light ends up being just above eye level.

Very good. Seeing ~2 inches of new leaf growth and its only been 2 weeks. My pitcher plant is finally producing pitchers again. Make sure not to put it too close to the plant or it will rouge the leaves

My monstera Burle Marx is growing so fast with this light!

Absolutely amazing grow light. My house plants are thriving.

L’éclairage donne de bons résultats pour mes plantes.

Great so far

Muy bueno, da muy buena Luz y le encantó a mis plantas

Excelente una semana y se notan los resultados, las plantas agradecen este tipo de luz cuando las tenemos en interiores con poca luz
